In the same vein as this question:

What's the best counter for Protoss Carriers?

It strikes me that templars are an excellent counter to mass carriers. Would utilizing Psi-Storm a couple times against carriers deal enough damage to destroy them? I imagine that a group of templars and a mothership would probably make this possible. Maybe vortex would also be of use here?

Or will a mothership/templars combo be destroyed too quickly to counter them?

  • I fear the latter, especially given the range of Carriers, they could fly out of the storm (at least a bit) while they still get to shoot at the Templar

  • If you thinking to build some carriers - you would better build more gateways/robos/starports for stalkers/immortals/collossus/voidrays. If your opponent build carriers - it means he doesn't spend all resources properly. If you both are playing more or less even and you detected protoss building a lot of carriers - build more stalkers/VoidRays. If Carriers attack from unreachable ground (rivers, etc) - go to his main/expansion - it will be GG.

  • @Ivo: Please note that Carriers move very slow to fly away. But indeed, will the Templars be able to hit the Carriers properly before they die? Seems not given Davy8 his stats... Commented Jan 28, 2011 at 17:44
  • @Budda: If you decided to go up the Templar Tech Tree earlier in the game, suddenly going for enough Void Rays to counter them takes a lot of time... Commented Jan 28, 2011 at 17:44

1 Answer 1


Assuming carrier user has equal or more attack upgrades as the HT user has armor/shield upgrades then a carrier will "1-shot" a HT in a single volley. It takes 1.5 seconds (with the interceptor release upgrade which anyone going mass carriers will have) to launch all the interceptors for the first volley, then they have a cooldown of 3 seconds, so averaging out first HT kill in 1.5 sec, then one every 3 seconds (theorycrafting based on Liquidpedia so if anyone had real measured numbers feel free to chime in)

It takes 6 full duration storms to kill a carrier, but realistically against a smart opponent you won't get full damage, especially if they're attacking from just in range, so it's more like 8-12 storms. Storm has range of 9, Carriers range out 8, however that's just 8 range to start attacking. They can move back up to 14 range after interceptors are out and still keep attacking.

Carriers are also pretty big, so unless they're intentionally clumping them together, you'd hit 3 max (guessing here) with a single storm. So 10 storms to kill 3 carriers, and presumably most of the HT aren't going to survive long enough to cast more than 1 storm (unless you have some other units like stalkers in the front line and you opponent doesn't specifically target the HTs)

That's 1500 gas in HT compared to 750 in carriers. Yes, they cost more minerals, however if you spent all your gas on HT's the only units you can build with just minerals are zealots which can't attack air, or cannons which can attack air but have shorter range than carriers.

You'll probably be able to kill off some interceptors to slow down the carriers, but I doubt it's enough to make a difference.

Even with the mothership's vortex if it's really mass carriers you're not gonna hit them all, again unless they're clumped intentionally for some reason. The cloak might buy enough of a delay to do something, maybe you can get off a 2nd storm, but you can only have 1 mothership, so it's going to survive maybe 5-10 seconds.

  • Sigh, add in the cooldown time and the fact that storms no longer stack, yeah, it is lame how weak the psi-storm has become.

    @alt storm was never meant to be good against "big" units. It's most effective vs large amounts of small units, i.e. terran bio, roach/hydra/ling (less so roach but still effective enough).
